To allcbhom'itmay concern." 5

'lt'lfllOWIl that I, GEORGE SCARFE, a" cit zen of the United States, residing at Nevada City, in the county of Nevada and State of California, have invented new and useful Improvements in Constant Flow Meters, of which the following is'a specification. a

meteig'and in particular to afmeter of the character descrlbed which 1s1ntended for use an measurlng water d scharging from" Y canals, ditches, tanks, orrs'ervbirsx: I:

One of the objects ofthe'present invention isto provide a meter which is particularly adapted for measuring and delivering a constaint volume of Waterwfrom canals or reserr vo'irs in which the water level is'likelyto vary, or, in other. words, where the water head in the source of supplymay changeat. any time. v '1 v V a;

Another object ofthe inventionis topr0-' vide'means for adjusting themeter to increase or decrease the volumeor flow; of water through same. v r I 1 Further objects will hereinafter appeaii The invention consists of the parts and the construction and combination of parts as hereinafter Hmore fully described and claimed, having reference to the accompanyingdrawingsin which Figurel is a plana-view--showing the application of the invention. -Fig. 2 is a ver tical section of 1. Fig. 3 is av plan' View of-the meter, showing it connected with a float. Fig. 4 is a detail view' of the inner tube; Fig. 5 is a detail view of the cylinder. Fig. 6 is a detail of the outer sleeve. Fig. 7

Referring to the drawings, A indicates a source of water supply, in this instance reprresented by a canal, B the meter, and Gthe meter-box. The meter proper consists, -pri'- marily, of a cylinder 2-, in the upper" side of ing at right angles thereto is an arm 9, on

the outer end ofwhich issecured a float 10.- Snugly fitted and turnable within the cylin-z der is a tubell, and formed in said tube is' an openlng 12 which is substantially-triad, H gular' in shape." The'hyp otenuse'of the tri- 1 angular opening is, hfowevencurved in this instance, as indicated 1 at 1'8, andthe' purpose I of said peculiar construction will later be described. I Oneend o'f'the tube '11 isop'n, I as indicated-at 14', while the other endl is' Iclosedby a head'15 which extends outside of the cylinder, and secured] to saidhead is a lever arm'16 byxvhich tl1e"head,with- =nectecl f y e turned. 1

Formed integral "with collar 5, or other- I w1se'secured t0'sa1ne,1s an upwardly extend f ing arm 17, on the upper end of Which is formed a segmental section 18. This seg- 'ment'. is graduated or has a scaleformed thereon, indicated at 19, and is also pro vided with-:a series of perforations 20 with 1 which arm 16 may be brought into register. .Arm 16 lSfPIOViClGd with a hole 21 and'it therefore, becomes possible to insert a pad-- lock 22, or any other suitable locking mechv anism, for securing arm'16, with connected K head, and tube lIlttfiXGd position. 7

; In actual practice, referring to Figs. 1' and 2, the device is connected as follows: .A pipe 23 is first driven'through the bank and connected with the meter box; a suitable form of strainer QAabeing applied for the usual purpose. The water level within the box, when thus connected, will natu rally correspond to that of the canal and will consequently' fall and rise as the level.

of the source of supply rises or falls. The meter is suitablysecured in the bottom of the boX and-theposition ofthe rec tangular openingformed in the sleeve will,

under normal conditions, register with'the opening in the cyhnder. Any increase or rise-of'water with n the 'bOX Wlll, however,

cause the float, with'connected lever,'to rise' and consequently turn the sleeve on-the outside of the 5 cylinder, f This s will cause the opening .7, in" the;-sleeve,ltopass :beyond 01' I out of. register withbpening 8' in the; cylinsx derv and-xwill 'consequently'reduce' the area of :same. i l a.

As an example, assumed that the i ter within the box, if the area of the dis-' charge opening was not reduced. The float, with connected sleeve, has, however, been provided for the purpoes of decreasing the area of the opening 3 in proportion to the increase of head of the water within the box.

A constant flow or discharge from the meter is thus automatically maintained regardless of the head. Means have also been provided for the purpose of adjusting the meter to increase or decrease the volume or flow of water through same; For instance, it is pos-. sible to set the meter to discharge two min'ers inches or it is possible to regulate the meter to ,clischarge three, four orlive .inches, or, any other desired quantity. The

tube 11 has been provided'for this purpose and the regulation of tllGflQW through the meter is accomplished by turning the tube in one direction or thezother so as'to bring ,opening 12 into or out of registerwith openmg 3 in the cylinder. If it is desired to cut down the amount, for instance, from :five miners inches to two miners inches, it is accomplished by turning the tube in the direction of arrow 01 or toward thexfloaTt, the

initial opening being thereby made smaller.

The shape of the opening or the curved line of the hypotenuse, above referred to,

is determined by the variation in flow which it is desired tosecure. The variation in head is, however, taken care of bythe sleeve and the float attached to same.

It can easily be seen, by referring to Fig. 3 that the area of the rectangulanshaped discharge opening, indicated at 3, may be easily increased or decreased by turning tube 11, so that the opening therein, indicated at 12, .will be brought more or less out of register. with opening 3, that is, Fig. :3 shows the tubular opening'in full register with opening 3; the meter being in this instance'setto its fullest capacity. If it is desired .to reduce the volume of flow through same, it is only necessary to turn the tube through the medium of lever 16 and head '15 in the direction of arrow a which will consequently reduce the area and the volume of water flowing through'same.

A meter constructed as here shown may be easily. adjusted by authorized persons and set to give thedesired flow as the graduated segment is marked from one to five which indicates the flow of the meter.

tampered with by placing a cover 25 over the,,b ox, which cover is secured by a suitable form of lock, indicated at 26.

The materials and finish of the several parts of the meter are such as the experience and judgment of the manufacturer may dictate.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1.
